I'd like to see an explanation why you believe society should cater to the recognition of certain forms of abnormal sexuality, and not others.
1. "Abnormal sexuality" is in the eye of the beholder, so no one person--or group, for that matter--should be telling any other adult what to do in the privacy of their own home with another consenting adult.
2. Homosexuality and pedophilia/bestiality are two very different things. A child or an animal cannot properly consent to sexual activity, while a reasonable adult can.
I'd like to see a response to these ideas.
